Use an Apache Reverse Proxy directive to expose a Solr endpoint.

#Reverse Proxy a Solr Instance#

It’s encouraged that you secure your Solr instance by placing the application on a different file server and behind a firewall. That’s an issue if you are trying to consume data from the Solr instance leveraging AJAX techniques.

##Problem##

• The website and Apache Solr live on separate boxes.
• A firewall protecting Apache Solr plus the cross-domain issue does not expose the necessary end-point to consume via AJAX.
• Depending on your sys admin setups, Solr may not live on a fully qualified domain (ie. http://12.34.56.789:8983/solr/#/)
• An AJAX call to consume the Solr instance’s JSON/XML won’t work cross-domain.

##Solution##

• Reverse Proxy directive, mod_proxy – Apache HTTP Server.
• This allows for an endpoint that is visible to the browser and we can consume the JSON/XML that rests within the Solr instance.
